Letters Patent No. 101,950, dated April 12, 1870.

IMPROVEMENT IN GRAIN-SCOURERS.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that I, VALENTIN WEISMANTEL, of Belleville, in the county ofSt. Clair and State of Illinois, have invented a new and usefulImprovement on a Grain-Scourer; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionandoperation of the same, reference being had to the annexed drawingsmaking part of this specification, in which i Figure 1 is a perspectiveview, and

Figure 2 is a transverse section.

The scourer consists of a conical drum, a, covered with lip-punchedsheet-iron, revolving on a shaft, h, driven by a pulley, 0, within thestationary shell I), covered on its inside with same description ofsheethen; this shell I) made in halves and held in place by beingfastened to top plate 6 and bottom plate 11, the whole mounted upon anordinary suitable frame 0.

Grain is admitted byt-he spout d, and received upon the dished top platef, of revolving cone a, wherefrom it is evenly discharged by centrifugalforce over its extremities between the rubbing or scouringsurfaces ofrevolving cone (0 and stationary shell b,.and after passing through thesecuring process falls to the bottom 2,- and is discharged at spout g.

The grain -operated upon by this machine will be caused to remainbetween the securing surfaces for a respectively longer space of timethan in other upright scourers heretofore in use, and will, by its resistance on the face of the revolving cone, relieve the toe of theupright shaft of part of its weight, thereby eeonomizing power indriving the machine.

The space between the faces of the cones can be regulated by lever K andhand-wheel L acting upon the center-lift tallow-pot m, of bridge-tree n.

The shaft is supported above in adjustable bearings p. i

I claim as my invention The conical drum a and shell I), constructedsubstantially as described, in combination with the lever K, screw L,and step m, arranged substantially as set forth, for the purpose ofregulating the amount of space between the drum a and shell b,.'asspecified.
